We will never sign 7 players. Before we signed Mata, Woodward said we can make 5 signings if we have a bad season.
Without any additions we will have the following squad at the end of this season.
GK
De Gea, Lindegaard
FB
Rafael, Buttner
CB
Jones, Smalling, Evans
CM
Carrick, Fellaini, Fletcher, Cleverley
RAM/LAM/CAM
Kagawa, Mata, *Januzaj, Nani, Young, Valencia
ST
Rooney, Van Persie, Welbeck, Hernandez
That's 20 players that need to be registered. Leaves us with 5 more additional spots to fill in our squad if Moyes plans to have a large squad. I think Cleverley, Buttner and Young are very likely to go this summer as they're clearly not good enough while Chicharito may leave to look for first team opportunities which will leave us even shorter even in terms of numbers.
When you look at that squad it becomes very clear that we need to add in that defensive and central midfield area.
You think Young, Cleverley and Büttner are likely to go while Nani and Kagawa would stay ? Sounds like wishful thinking. Ofcourse we don't know who is going and who is staying but if if the reports in the media are anything to go by kagawa, Hernandez and Nani (been linked with a move to the serie A now for over a year) are the ones who might be leaving while I have read nothing about Young (his salary is also so high nobody will want to sign him from us) and the only article I saw about Cleverley was the club wanted to give him a new 5 year deal and Büttner is our only leftback if Evra leaves I don't think it is likely we will sell unless unless we bring in atleast 2 players who can cover that position (which I think is unlikely). Also where is Giggs on your list after his display at Olympiakos and his quotes after the game I think it is likely he'll be a part of our squad next season aswell.
Players I think are more or less
certain to leave: Vidic, Ferdinand, Evra
Players: who are
likely to leave: Nani
Players who
might leave: Kagawa, Hernandez
Players that could leave but
not likely: Young, Cleverley, Büttner
Players who are more or less certain to
stay: Rooney, RVP, Welbeck, Valencia, Januzaj, Mata, Fellaini, Carrick, Fletcher, Giggs, Rafael, Evans, Smalling, Jones, DDG, Lindegaard
In short that are 16 players who are likely to be here next season and 9 who might be leaving in the summer. Januzaj is under 21 so he doesn't count towards the 25 player limit which basically leaves us with 10 potential player spots to fill in. Some of those will be filled in by players that I've listed under might be leaving (that will stay) and some will be filled in by new signings. Also the squad may be enlarged by signing up players from under 21, from our own youth Varela and Keane sound like plausible additions and if we'd buy Shaw he'd also not count to towards the limit (for example)
So basically it depends on the amount of players that will leave in the summer. If only Vidic, Ferdinand and Evra leave we'll have 4 available spots for new players over 21 in the team. Other spots will depend on players leaving, I don't think it is unlikely we could see 2 or 3 additional players leaving which would permit us to sign 6-7 players over 21 if we wish to do so (which doesn't mean we will but we can if we want to).
The 25 man limit won't be a problem for bringing in our targets, the only problems we'll have is convincing the players without CL football and the financial constraints of our budget.
For example:
Out: Vidic, Ferdinand, Evra, Nani, Kagawa
In: Coentrao, Mangala, De Sciglio, Carvalho, Kroos, Lucas Mourra, Varela
Squad for next season:
Attack
Rooney, RVP, Welbeck, Hernandez
LM/LW RM/RW CAM
Mata, Januzaj, Valencia, Young, Lucas Mourra
Midfield
Kroos, Carrick, Giggs, Cleverley, Carvalho, Fellaini, Fletcher
Central Defence
Mangala, Evans, Smalling, Jones
Fullbacks
Rafael, Coentrao, De Sciglio, Büttner, Varela
GK
DDG, Lindegaard
25 players over 21
11 of which are homegrown
and 2 additional players under 21
